Brain of Cthulhu
It just occurred to me to test if conveyer belts work upside down. They do, but there's more. I remembered reading a report that asphalt does not work upside down, so I thought I'd recheck that. Guess what? Now it does. I also tested frozen slime, pink slime, and honey blocks. All of these work as expected, except honey blocks, which have an ever greater slowing effect when you stand on the underside for some reason. You can barely walk at all.
I'm not sure how well known any of this is, but it should make for some interesting maps.
